Identically shaped PCB terminal blocks with Push-in spring connection

Identically shaped PCB terminal blocks with screw connection

Versatile connection technology for PCB terminal blocks

Our product range of PCB terminal blocks offers you a unique variety of connection options – from the established screw connection to the IDC fast connection through to the innovative push-in technology.

Overview of the connection technologies

Screw connection with wire guard

Wire guards are particularly suitable for semi-industrial applications such as building automation, safety technology or telecommunications. The connection method is distinguished by high reliability with inexpensive setup.

Screw connection with tension sleeve

Connect industrial applications with high contact reliability requirements using the world's most frequently used connection method worldwide. Very high contact forces can be achieved with the screw connection, irrespective of the conductor cross section.

Front screw connection

Cable routing and actuation of the terminal block screw on one level – front screw connection for narrow device fronts and PCB racks. The conductor is reliably clamped by the force-increasing swiveling movement of the angled pressure plate.

Push-in spring connection

Whether it's a push-in spring or a leg spring, the spring principle enables fast conductor connection without the need for tools. Simply insert the solid conductors and conductors with ferrules into the push-in terminal point and loosen by pressing the different color trigger. When connecting and loosening finely stranded conductors without ferrules, the terminal point can also be opened using an integrated spring trigger.

Push-lock spring connection

The push-lock spring makes for the quick, tool-free connection of both solid and flexible conductors with and without ferrules. Simply insert the conductor into the open terminal point and connect it by actuating the tilting lever via the push-lock spring. Alternatively, the conductor can be inserted into the closed terminal point using push-in technology.

Push-in spring connection with screwdriver activation

Whether it's a push-in spring or a leg spring, the spring principle makes for quick, tool-free conductor connection. Simply insert the solid conductors and conductors with ferrules into the push-in terminal point and release using a screwdriver. When connecting and releasing finely stranded conductors without ferrules, the terminal point can also be opened using a screwdriver.

Spring-cage connection

Spring-cage technology enables easy connection without the need for special tools or conductor pretreatment. Open the spring using a screwdriver and push the conductor into the spring cage through the separate conductor shaft.

Insulation displacement connection (IDC)

The IDC insulation displacement connection is a particularly time-saving connection technology. When this connection method is used, the IDC metal displaces the insulation and creates a reliable connection.

Always the right mounting type for your requirements

The comprehensive product range of PCB terminal blocks offers you solutions for various different manufacturing process. This means that you can assemble printed-circuit boards efficiently and process safely.

Overview of mounting types

Wave soldering

Wave soldering is the standard soldering process for manufacturing electronic modules that are predominantly assembled using wired components. A characteristic of this is a solder contact protruding through the PCB which is soldered onto the underneath of the PCB.

SMT soldering

SMT stands for surface mounting technology. Elements are mounted on the PCB surface in solder paste and soldered using the reflow soldering procedure. This method requires special components with the corresponding surface contacts.

THR soldering

Through-hole reflow soldering (THR) enables the integration of high-temperature material, wired components into the SMT reflow process. The through-hole contacts are inserted through the drill holes filled with solder paste and soldered using the reflow soldering procedure.

Accessories and convenient functions for maximum versatility

Our PCB terminal blocks offer you a large number of convenient functions and comprehensive accessories for maximum user-friendliness during connection and maintenance.

Overview of convenient functions

Individual marking

Monoblocks as well as individual side-by-side terminal blocks allow printing, marking, and color coding. This simplifies installation and reduces the risk of incorrect wiring.

Compact design

The largest possible clamping space can be achieved in even the smallest dimensions. You benefit from high levels of connection convenience and a wide range of connection options – even if space is limited or the design is restricting.

Integration into the device front

Thanks to uniform design and flushed housing ends, it is possible to optimally integrate PCB terminal blocks from Phoenix Contact into the device fronts. This enables you to implement economic panel feed-throughs based on the standard range.

Solutions for SMT and THR

Integration of components into automated assembly processes reduces lead times and process costs. Whether it's tape on reel, tube or tray: we supply our components for SMT and THR processes in standardized packaging or packed for automatic devices.

Multi-level versions

Multi-level versions enable space-saving connection of several levels. Multi-level versions are available both for wave and THR soldering processes.

Safe mounting flange

PCB terminal blocks for high currents up to 232 A also have an additional mounting flange. This allows you to connect the PCB terminal block with screw flange to the PCB and relieve the strain on the solder pins.

Multi-row arrangement

Versions with angled conductor outlet allow a particular high connection density on the PCB. This enables you to arrange the PCB terminal blocks from Phoenix Contact in several rows and save space.

Easy potential distribution

The fixed or plug-in bridges enable you to easily connect individual positions or terminal block bases to each other in order to distribute potentials or loop through grounding conductors. In the case of internally-bridged versions, the full clamping space remains.

Integrated test connections

Numerous product ranges are equipped with integrated test connections for service work or for tracing faults. This allows you to carry out measuring conveniently without removing the wiring or other accessories.
